Sobo Sponge Filter

Sobo Sponge Filter

Mechanical & Biological Filtration for Aquariums

The Sobo Sponge Filter is a simple yet highly effective solution for both mechanical and biological filtration in freshwater aquariums. Designed to trap debris while promoting the growth of beneficial bacteria, it helps break down harmful ammonia and nitrite—ensuring cleaner, healthier water for your fish.

Operating silently with the aid of an air pump (sold separately), the filter also oxygenates the water as it works, supporting overall tank health. Its sponge media is ideal for delicate species such as fry and shrimp, and it’s easy to clean and reuse.

Key Features:

• Provides mechanical filtration by trapping debris

• Offers biological filtration by supporting beneficial bacteria colonization

• Helps oxygenate aquarium water through air-driven circulation

• Safe for small or delicate fish and fry
